BACKGROUND ART

In general, in order to build a reinforced concrete building, aframework of the building is constructed by arranging reinforcing barsto form a frame of the building, installing a plurality of formwork onoutsides of the frame, pouring concrete, and then curing the concretefor a specified period.

Such a formwork composed of a plurality of wood panels is not onlytime-consuming to manufacture, but is also impossible to reuse becausemost of the formwork is broken in the process of removing the formworkafter curing the concrete. Also, it is impossible for a scaffold,separately installed for building-exterior work and reinforcing-barwork, to be recycled once the use of the scaffold is finished.

Therefore, in recent years, large formwork called gang form cages, whichare installed outside of buildings during concrete pouring, have beendeveloped and necessarily used in constructing high-rise buildings. Thegang form cage is made of a gang form providing a concrete pouringsurface and a working platform connected to the gang form to provide aworkspace.

The gang form cage is set to be temporarily fixed by bolt-fastening, toouter wall surfaces corresponding to each floor while being moved to aspecified height by a tower crane so that the outer wall of the upperfloor is lifted in consecutive order and constructed starting from thelower floor of the concrete structure.

Meanwhile, in recent years, efforts have been made to eliminate the workload of the tower crane by providing a cylinder for lifting the cageintegrally equipped with the cage on one side of the gang form cage.

As an exemplary embodiment of the gang form cage as described above,there is a construction climbing system with a climbing shoe or a guideshoe, which was registered with Korean patent No. 10-1152963(Registration Date: May 29, 2012).

This construction climbing system includes: at least one climbingbracket 12 for supporting a formwork; at least one climbing profile 14disposed in the climbing direction with respect to the building; and atleast one climbing shoe or guide shoe 10 which may be installed in abuilding or the climbing bracket 12, and interacts with the climbingprofile 14 for a climbing operation.

The climbing shoe or guide shoe 10 is characterized as having at leastone brake 18 acting on the climbing profile 14, and in that the brake iscoupled at all times to the climbing profile by receiving transferredpretension for the climbing profile 14.

In another embodiment, the climbing system with Utility ModelRegistration No. 20-0445741 (Registration Date: Aug. 20, 2009) ischaracterized as including

a shoe 200 attached to the building wall 100;

a rail 300 connected to the shoe 200 and provided with a plurality oflocking protrusions 320;

a cylinder 500 coupled to the shoe 200;

a support member 600 connected to a hinge shaft 630 on the top of thecylinder 500,

whereby a rotation limiting groove 675 is provided adjacent to the hingeshaft 630 and a support member 600 is provided with a protrusion 640located in the rotation limiting groove 675,

and the support member 600, which is moved downward as the cylinder 500is reduced, is pivoted about the hinge shaft 630 when colliding with thelocking protrusion 320.

However, in the conventional gang form cage as described above,connecting bolts protrude to both sides in the process of connecting aplurality of rails connected to the shoe attached to the building.Accordingly, in the process of lifting the gang form cage upward througha lifting device, the connection bolts protruding from the shoe areeasily caught, and thus lifting work may not be performed smoothly.

In addition, in the case of the gang form installed in the cage,demolding work is not easily performed in the process of the demoldingafter pouring and curing the concrete. Accordingly, as the workersperform the demolding work in narrow cages, the demolding process isvery difficult and dangerous, and thus the work stability of the workersis not guaranteed.

Also, in an effort to ensure the work stability of the worker asdescribed above, an auxiliary scaffold is installed in the front part ofa working scaffold installed in the cage and tries to improve workstability by expanding the working range of the worker. However, sincethe auxiliary scaffold to be installed does not have strong support dueto connecting to the existing working platform by hooking or bundlingwith wire, there is a problem that a severe industrial accident such asfalling of a worker may occur when the connection state of the wire ispoor.

As shown in the drawings, the construction climbing system with improvedstructural stability according to the present invention (hereinafter,referred to as a “climbing system”) 1 largely includes a cage 100provided in a structure or a building so as to be movable in thevertical movement, and a gang form 200 installed in a structure capableof moving forward and backward on the top of the cage 100.

The cage 100 has a frame 10 designed to have a height corresponding toone or two or more floors of a structure or building to be constructed,and a predetermined width and depth; a plurality of working scaffolds 20installed inside the frame 10; a shoe 300 installed at one side of theframe to be installed in a building; and a climbing rail 30 assembled ina sliding-movable form.

The frame 10 is made as a unit of a predetermined standard to form anoverall outer shape of the cage 100 of the present invention. That is,the frame may be assembled into a grid-like form by using a conventionalsteel frame, for example, a square pipe, including channel-shaped steelbeam or H-shaped steel beam and the like.

In addition, the size of the frame 10 may be manufactured in anappropriate size in consideration of various site conditions, such asthe size of the building to be constructed. In the case of a generalbuilding, it is proper that the width may be about 6 m to 15 m, and inthe case of height, the height may be to cover about 2 to 4 floors, andthe depth may be about 0.6 to 1.2 m.

In addition, the guidance rail 30 is assembled to one side of the frame10 and a protective screen (not shown) such as a PE net, a wire mesh, ora tent is attached to the other side of the frame 10 to prevent fallingthe workers or falling objects, or to prevent dust or foreign substancesgenerated during operation from flying into the air.

In addition, although the frame is shown to cover the height of the twofloors of the building in the illustrated embodiment, a specific sizemay be adjusted in discretion according to conditions of a constructionsite. In addition, although not shown, it may be sufficiently consideredfor the frame 10 provided in a lattice shape to be structurallyreinforced by a turn buckle or bracing as necessary.

The working scaffold 20 is to provide a space in which the workerworking inside the cage 100 may safely work, and is assembled to theframe 10 as shown in FIGS. 7 to 9. Also, the working scaffold includes:a plurality of support bars 21 made of the same pipe or channel sectionsteel, the same as the frame 10; a perforated scaffold 27 assembled tothe upper part of the support bar 21; and an extension bracket 23 towhich the auxiliary scaffold 24 is assembled to one side thereof andcoupled to the frame 10 and the support bar 21.

The perforated scaffold 27 provides a protruding hole 271 protrudingfrom the edge of the hole (not shown) to the upper part to prevent theworker from slipping during the work on the perforated scaffold.

The extension bracket 23 are integrally provided with a first fittinggroove 261 to which the frame 10 is fitted at the bottom thereof and asecond fitting groove 262 to which an auxiliary support bar 241 of theauxiliary scaffold 24 and the support bar 21 of the working scaffold 20is fitted at the top thereof, and a plurality of fastening holes 263.Accordingly, the support bar 21 and the auxiliary support bar 241 arebolted to the second fitting groove 262 in a state in which the frame 10is fitted into the first fitting groove 261 to be firmly fixed with abolt (not shown). Therefore, the auxiliary scaffold 24 is connected tothe frame 10 and the working scaffold 20 to maintain a firmly providedstate.

In addition, the auxiliary scaffold 24 includes the auxiliary supportbar 241 in which one side thereof is fastened to the second fittinggroove 262 of the extension bracket 23 and an auxiliary perforatedscaffold 242 assembled on the upper part of the auxiliary support bar241.

Particularly, as an inclined surface 243 is provided at the endconnected to the extension bracket 23 of the auxiliary support bar 241,the auxiliary scaffold 24 is rotatably provided without being caughtupward in a state assembled to the extension bracket 23. Accordingly,when not being in use, the auxiliary scaffold 24 may be eliminated byremoving it from the extension bracket 23 or by removing only a part ofthe fastening bolt and rotating the upper part to prevent the cage 100in motion from being caught by the auxiliary scaffold 24.

Before being assembled and provided on one side of the frame 10, theclimbing rail 30 is provided in such a manner that the climbing rail 30has the same or similar height as that of the frame 10 by connecting aplurality of climbing rails to each other, like a prefabricated frame10.

That is, the climbing rail 30 integrally provides a locking rack 32having a wedge-shaped tooth inclined to one side between a pair ofC-shaped steel beam 31 as shown in FIG. 2.

At this time, the locking rack 32 coupled between the C-shaped steelbeam 31 protrudes from the end part thereof to the lower part of theC-shaped steel beam 31 to form a protrusion 322 having a connection hole321. Also, the climbing rail provides a housing groove 312 havingconnection holes 311 at both sides with the same depth as the length ofthe protrusion 322 on the upper part thereof to connect to theprotrusion 322 of the locking gear 32. Accordingly, the protrusion 322is inserted into the housing groove 312′ of the climbing rail 30′ sothat each of the connection holes 311′ and 321 is located in the sameline, and then climbing rail 30 and 30′ are firmly connected to eachother by being fastened with a fastening member 33.

In addition, since the fastening member 33 minimizes the part protrudingto the outside while maintaining a firm connection state in connectingthe plurality of climbing rails 30, the climbing rail 30 is not blockedin movement by minimizing jamming with the shoe 300 when the shoe 300 isin close contact with the outer surface of the climbing rail 30afterward.

That is, the fastening member 33 penetrates the respective connectionholes 311′ and 321, and includes a female coupler 331 composed of afemale screw hole 3311 and a convex lens-shaped female screw head 3312,and a male coupler 332 composed of a male screw body 3321 screwed intothe female screw hole 3311 and a convex lens-shaped male screw head3322. The fastening member 33 is to screw the male screw body 3321 ofthe male coupler 332 to the female screw hole 3311 in a state that thefemale coupler 331 is inserted into the connection hole 311 and 321 soas to expose the screw heads 3312 and 3322 of the male coupler 332 andthe female coupler 331 to the outside of the connection hole 311′.Accordingly, when the climbing rail 30 moves while being connected tothe shoe 300, only the convex-type screw heads 3312 and 3322 are exposedin minimum to ensure stable movement of the climbing rail withoutshaking due to the locking. Accordingly, when the climbing rail 30 isconnected to the shoe 300 only the convex lens-shaped screw heads 3312and 3322 are at least exposed, thereby ensuring stable movement of theclimbing rail without shaking due to the locking.

Meanwhile, the gang form 200 is provided in a form that is movableforward and backward in the upper part of the cage 100, and includes: abase 210 assembled in a slidable form with the frame 10 in the lowerpart thereof; a moving frame 240 assembled with the frame 10 in avertical direction; and an inclined support strut 250 which maintainsthe fastening state between the base 210 and the moving frame 240.

The base 210 is composed of a fixed base 220 fixed to the cage 100 and amoving base 230 assembled to be slidably movable with the fixed base220. Since the moving frame 240 in which the formwork is installed onone side of the moving base 230 is assembled with the fixed base 220 bythe inclined support strut 250 and installed in a form in which theinclination is adjustable, the base 210 ensures that the wall surface isbeing built in a state exactly perpendicular to the floor surface.

The fixed base 220 has a pair of C-shaped steel beam 224 facing to eachother, and includes: a protruding part 221 positioned on one sidethereof, and which may be caught by the shoe; a spacing plate 222 on theother side thereof; a part of the rack gear 223 protruding upwards inthe middle thereof.

The moving base 230 is fixedly spaced apart at regular intervals by amethod such as welding a plurality of fixed plates 233 having aninsertion groove 232 in the lower part in a state in which the pair ofC-shaped steel beam 231 is faced to each other. Also, the moving basemay include: a first connection part 234 rotatably assembled with alower part of the moving frame 240 on one side thereof; and a secondconnection part 235 rotatably assembled with the inclined support strut250 on the other side thereof; and a gear 236 meshed with the rack gear223 at a central part thereof, and rotatably assembled inside the pairof C-shaped steel beams 231, and a locking protrusion 237 protrudesoutside the pair of C-shaped steel beam 231.

The fixed base 220 and the moving base 230 configured as described aboveare inserted into the insertion groove 232 of the moving base 230 by theupper part of the fixed base 220, so that the gear 236 of the movingbase 230 is meshed with the rack gear 223 of the fixed base 220. At thesame time, the lower surface of the C-shaped steel beam 231 of themoving base 230 is in close contact with the upper surface of theC-shaped steel beam 224 of the fixed base 220. Accordingly, in a statein which the moving base 230 is in surface contact with the uppersurface of the fixed base 220 and stably supported, a wrench (not shown)is connected to the locking protrusion 237 protruding to both sides ofthe gear 236. Also, by manually rotating the gear 236, the moving base230 is moved back and forth from the fixed base 220.

Moreover, the rotation of the gear 236 may be driven manually through awrench (not shown) as described above, and in another embodiment, thegear 236 may be automatically controlled through a connection with adrive motor (not shown).

Also, the gang form 200 is fastened due to a protruding part 221protruding on one side of the fixed base 220 by being caught by the shoe300 installed on the building, thereby preventing workers from fallingand ensuring the stable driving of the gang form 200.

In this embodiment, the finishing cage 400 having anextended working scaffold 410 for the finishing work of the building isintegrally provided at the lower part of the cage 100. Accordingly,since it is not necessary to provide a separate temporary facility forexternal work of a building, the overall construction period of thebuilding may be shortened, thereby reducing the temporary constructioncost and construction period.

Meanwhile, FIG. 11 is a view showing a modified embodiment of the cageof the construction climbing system with improved structural stabilityaccording to the present invention. In the present embodiment, aconfiguration of the gang form among configurations of the climbingsystem is removed, and the climbing system is reconfigured with only thecage to perform an external finishing work of the structure.

In addition, FIG. 12 shows a modified mode of the cage shown in FIG. 11.As shown the above, an auxiliary cage 400 is provided to slidably moveto both sides in the cage so as to expand the workspace to a wider form,thereby securing an exterior working space more efficient.
